T all whom it may concern:

Be it known that I, Aueusrus SEAVER, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvemeuts in the Method of Making Unturned Boots and Shoes, of which the following is a speeification.

This invention has forits obj ect to cheapen the cost of manufacture of boots and shoes in which the upper is lasted right side out and secured to the sole by stitches or other fasteningspassed through the sole and the edge of the upper. Y

The invention consists in an improved method comprising the following steps, viz: I first place the upper right side out on the last, using stitches or other means to secure it in place on the last, no inner sole being used. I

then coment the sole to the outer surfacesof the edges of the upper on the bottom of the last,and, lastly,l remove the upper and sole and perma- 4 nently connect them bystithes or any suitable in which Figure l represents abottom view of the last and upper after the upper is secured to the last. Fig. 2 represents a section on line x ac, Fig. 1. Fig. 3 represents a similar section, showing the sole cemented to the upper. Fig. 4 represents a longitudinal section of the completed shoe. v

The same letters,of reference indicate the same parts in all the figures.

In carrying out my invention,l place the upper a on a last, b, and secure the edges of the upper, either by stitches c, as shown in Fig. 1, or by any other suitable means, in such manner as to 'retain the upper upon the last without preventing its removal from the last. I then coment to the outer surfaces of the edges of the upper, whichle upon the bottom of the last, a sole, e, using in the cementing operation a sole-laying machine having a molded yielding soleshaped pad,which presses the cementcoated sole against the edges of the upper and molds or conforms the sole to the shape of the bottom of the last, the molded sole and upper being held in shape by the coment connection. When the cement has suflicientlyset,l remove the cement connected and molded upper and sole and permanently unite them by stitches or other fastening f f, as shown iu Fig. 4. The shoe is now substantially completed. and requires only a covering of cheap and thincloth, morocco, or other suitable material on the inner surface of thesole and the edges of the upper secured thereto.

It will be seen that by this method Ivdispense with an inner sole,and thcrebynot only cheapen the cost of manufacture, but also make a Shoe that is extremely flexible and easy to the foot.

I claim The improved method of making untgr nred boots and shoes provided with a single sole,the same consistingiu removably securing the upper to a last right side out, pressing a cement- AUGUSTUS SEAVER.
